Least-squares spectral analysis in WarpScript

[Pierre Zemb]

Hi! 

I'm currently playing with WarpScript for a fun side-project: finding exoplanets. Most astronomers and astrophysics guys are using periodogram to search for periodicity with functions like "Lomb-Scargle Periodogram". As you can see here in this python notebook, it provides nice and easy analysis to find the period. I tried achieving the same results using FFT but it was difficult to interpret the result.

Could it be a nice addition to WarpScript? What do you think?

Given the narrow field of application such a function probably does not belong to the core language, but you can provide an AstroWarpScriptExtension which would include this and other algorithms useful for astronomy and astrophysics.

Thanks Mathias for your reply, I will write some AstroWarpScriptExtension to do the job!
